One of the subcategories used by the WEF is the prevalence of organised crime — listed under the "security" index. Extortion, racketeering, theft, violence, and property damage are all factors that could hold back a country's development.

To make the comparisons more reasonable, we only took countries from the Organisation of Economic Cooperation and Development (OECD). There are 34 nations, all democracies with mixed or market economies. The group is often though of as a rich countries' club.

We looked at the 11 worst OECD countries for organised crime. The lower the WEF ranking given, the worse the country is for organised crime. Some major economies, such as Russia, are not currently members of the OECD.

Here is the list.
